With three straight top-three finishes, a new stadium, and their star player signed to a new long-term contract, the future is bright at Tottenham Hotspur.

Yet a lack of reinforcements from the transfer window could loom large early as Spurs open their season for the second straight year at St James' Park on Saturday against a Newcastle United squad again embroiled in self-inflicted turmoil.

Tottenham (23-8-7 in 2017-18) had 12 players take part in the World Cup this summer, third-most in the top flight behind Manchester City (16) and Chelsea (14). Three Lilywhites - Kieran Trippier, Dele Alli and Harry Kane - were full-time starters for England while Eric Dier and Danny Rose made multiple starts as they reached the semifinals.

Additionally, goalkeeper Hugo Lloris backstopped France to their second World Cup title while centre backs Toby Alderweireld and Jan Vertonghen along with midfielder Mousa Dembele claimed third place with Belgium, who beat England twice. Christian Eriksen (Denmark) and Davinson Sanchez (Colombia) both progressed to the round of 16, with Sanchez losing to his English teammates.

Heung-min Son was the only Spurs player not to reach the knockout round, but his South Korea side sprung one of the biggest upsets in Russia by defeating 2014 champion Germany.

All these players are just returning to camp and coupled with dual-track responsibilities domestically and in Champions League, chairman Daniel Levy was curiously inactive as Spurs made zero personnel moves coming or going in the summer window. Levy made a late charge at Aston Villa midfielder Jack Grealish but was rebuffed by the Championship side as his £25 million offer was deemed insufficient by new ownership.

Levy, however, blew open his carefully built wage scale for Kane, the Golden Boot winner in Russia with six goals as he signed a new six-year deal in June worth a reported £90 million only 11 months after putting pen to paper on his previous contract.

This new deal, worth £200,000 per week, recognizes the value of the 25-year-old striker who scored 79 goals in the last two seasons in all competitions, narrowly missed winning a third straight Premier League Golden Boot last spring, and is the face of English football as talisman of the Three Lions.

The other big contract was signing manager Mauricio Pochettino to a five-year extension worth over £40 million through 2023 in May, tying together the fates of star player and gaffer.

"Daniel and I have spoken at length about our aspirations for this football club," Pochettino said at the time of his signing. "We both share the same philosophies to achieve long-term, sustainable success. This is a special club - we always strive to be creative in the way we work both on and off the pitch and will continue to stick to our principles in order to achieve the success this club deserves."

Kane's new deal raised eyebrows among his teammates, many of whom experienced difficult negotiations with Levy. Alderweireld was hoping Manchester United would pry him from White Hart Lane, and Rose expressed his desire last season to find his market value with his next deal at Spurs or elsewhere.

On the pitch, the 4-2-3-1 Pochettino prefers should see little change from last season, though Sanchez now occupies the centre back spot Alderweireld once held. Dier may have supplanted Victor Wanyama as a midfield partner with Dembele, and the attacking quartet of Kane, Alli, Eriksen and Son remains intact.

A higher-up not spending money is nothing new for Newcastle United manager Rafa Benitez, who has seemingly been at odds with club owner Mike Ashley since taking over the club in 2016. The Spaniard did yeoman's work last season with what was essentially the same side that won promotion from the Championship in 2017 as the Magpies (12-8-18) finished 10th mainly on player graft and coaching guile - their 39 goals were second-fewest among top-10 clubs.

This summer, the soap opera renewed as Ashley again promised Benitez he would open the purse strings and never fully delivered. This created fresh enmity between owner and supporters, the latter of whom share a two-way street of adoration with Benitez and fearful he will quit St James' Park after one empty promise too many.

The Toons made targeted moves this summer - centre back Fabian Schar, defensive midfielder Ki Sung-yueng and forward Yoshinori Muto all signed for a combined total of less than £13 million - and Ashley kept a hawk's eye on the balance sheet as Newcastle off-loaded striker Aleksander Mitrovic to Fulham for £22 million.

Newcastle secured winger Kenedy on loan from Chelsea for a full season, and Benitez will work on Salomon Rondon as a reclamation project after being loaned from West Bromwich Albion in exchange for Dwight Gayle. The Magpies also signed keeper Martin Dubravka on a permanent deal after he arrived in January from Sparta Prague. Right before Thursday's deadline, they added defender Federico Fernandez from Swansea City.

While friction between Benitez and Ashley is nothing new, the same holds true for players and owner. They boycotted "walk-up" media duties for broadcasters for one day due to a row over bonus payments Ashley promised from both the FA Cup and last season's finish. It was resolved Wednesday, and captain Jamaal Lascelles is looking forward to leaving all the distractions behind.

"We've managed to sort the off-field stuff; now that's out of the way, we don't have any reason why we can't go out and put on a good performance," he told Newcastle's official website. "Everybody looks sharp, we're training hard and we've all got our heads in the right place."

Benitez is counting on a standout season from midfielder Johnjo Shelvey, one of the league's most creative yet mercurial playmakers. The 26-year-old nearly made England's World Cup squad after heeding his manager's call to be more under control - Shelvey was not disciplined the final 15 matches after being ejected twice in the first 13.

One of those red cards came in last season's opener when he needlessly stamped on Alli's ankle in the 48th minute and swung the match in Spurs' favour. Alli would get the last laugh with the first goal just after the hour and Ben Davies added a second nine minutes later for a 2-0 win.

Tottenham did the double over Newcastle last season and have won three of their last four at St James' Park.
